Quantized Output Feedback Control for a Class of Strict-Feedback Nonlinear Systems

摘要

In this paper, the issue of filter-based quantized output feedback control is investigated for a class of strict-feedback nonlinear systems. The considered systems contain immeasurable states and input quantization. A fuzzy filter is designed to estimate immeasurable states, and the hysteretic quantized input is used to eliminate the oscillation phenomenon. Based on the backstepping recursive technique, a new fuzzy adaptive output feedback control method is developed. Finally, simulation results are given to confirm the validity of the proposed method.
